Background

For transfemoral (above knee) amputees, daily situations such as climbing stairs or standing up from a chair can become difficult challenges. Especially old and weak people are often not able to overcome these obstacles without help.

Task

Working with Ottobock HealthCare GmbH, a world leading prosthetics company, Paul developed a prosthetic knee joint, that supports especially old people while sitting down and standing up from a chair. The project included the following tasks:

Biomechanical description of the sitting down and standing up process

Development of different possible concepts for supporting these situations

Design and final realization of a first prototype

Evaluating the prototype with human subjects

Outcome

First, a scientific reliable biomechanical analysis was developed that helps evaluating further developments. Afterwards, a first prototype was realized, which can be tested in real-life conditions and is going to be optimised continuously going forward.
